UNITED STATEs PATENT OFFICE.

JAMES H. GLASS, OF MGREGOR, IOWA, ASSIGNOR, BY MESN E ASSIGNMENT,

TO LOUISA J. GLASS.

IMPROVEIVIENT'INV GANG-PLOWS.

Specification forming part of Letters Patent No. 117,404, dated July 25,1871.

To all whom t may concern:

Beit known that I, JAMEs H. GLAss, of Mc- Gregor, in the county ofClayton and State of Iowa, have in venteda new and valuable Improvementin Gang-Flows; and I do hereby declare that the following is a full,clea-r, and exact description oil the construction and operation of thesame, reference being had to the annexed drawing making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawing is a top view of my invention. Fig. 2 is acentral vertical section of the same. Figs. 3 and 4 are detached viewsof the same. Fig. 5 is a partial front View and section.

rllhis invention has relation to certain improvements in gang-plows,consisting in the application and arrangement of devices for the purposeof regulating the depth and number of furrows, guiding the implement inits course, and otherwise` increasing its utility, as hereinafterdescribed.

In the accompanying drawing illustrating this invention7 A representsthe axle, and B B the driving-Wheels of a gang-plow. The latter arejournaled to the boxes O, ianged at d to slide vertically onguiding-plates D secured to the ends of the axle A, and holdingscrew-studs d', through which Work crank-screws d", the turning of whichraises or lowers the wheels, so that one may be made to run in a furrowwhile the other passes over the solid ground, the axle remaininghorizontal. E denotes an oblique beam, hinged at one end to one side ofthe axle A and at the other holding a caster-Wheel, F, which is securedto a box, arranged and operating to raise or lower the caster inprecisely the same manner as those marked C, and already described,operate to raise the wheels B. These boxes preserve the screws fromrusting or clogging up. G represents a longitudinal beam, bolted to theupper side of the oblique beam E. The former extends over the axle,passing through a loop, H, rising from the axle. To the forward end ofsaid longitudinal beam a frame, marked I, is secured, and to the ends ofsaid frame notched semicircular plates I bolted. I" denotes arms pivotedto and outside the plates I', and coupled, by rods J, to the bentplow-beams J', which are pivoted to long channeled boxes J", so formedto render the plowbeams firm, attached to the upper side of the obliquebeam E. The moving of the :arms I" raises or lowers the plows to anydesired point, so as to adapt them to the depth of furrows, as may bedesired. The notches K, formed on the edges of the notched plates I',are intended to hold the ends of the dogs K', which arepivoted to lugs7c projecting om the arms I", and have bent ends which enter the notchesk through slots cut in said arms. The dogs are held engaged to thenotched plate by springs L, and are used for the purpose of holding theplows at any desired elevation. L' indicates guiding-anges overlappingthe plates I'. The relative angles of the axle and oblique beam maybechanged, by reason of their being hinged together. When the axle isturned back toward the beam it may be held by means of the chain M andshackle N, which also render it adjustable. A dog, O, pivoted to theside of the longitudinal beam G, and formed with a beveled hooking end,is employed to hold the axle at a right angle to the longitudinal beam.One end of said dog projects through a slot in the frame I so as to bewithin reach of the drivers foot, he being seated on the elevated seat.Q denotes the draft-pole, hinged to a transverse rod, Q', which isarranged underneath the axle, and of such a length as to allow thedraft-pole considerable lateral adjustment, which is regulated by ascrew, It, passing through one or both of the hinges It'.

I claim as my inventionl. The box G, opera-ted as described, and servingas a protection for the screw and studs el', in

combination with the flanged plate D, constructed and arrangedsubstantially as specified.

2. The dog O, in combination with the chain M, shackle N, hinged beam E,axle A, and beam G, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JAMES H. GLASS.
